ObjectiveTo systematically evaluate the efficiency and safety of interventional embolization versus laparoscopic surgery in the treatment of varicocele. MethodsWe searched the Chinese Journal Full-text Database, Wanfang Medical Journal Database, and VIP Chinese Science and Technology Journal Full-text Database with such keywords as interventional therapy, embolization, laparoscope, and varicocele. For PubMed and Cochrane Library, MESH terms or keywords were interventional embolization, interventional therapy, embolization, laparoscope, laparoscopic surgery, and varicocele. All database were searched up to March 2015. Then we selected trials comparing interventional embolization versus laparoscopic surgery in the treatment of varicocele according to the including criteria. We assessed the quality of the included studies with the Newcastle-Ottawa Scale and conducted meta-analysis with revman 5.2 for the primary outcomes sperm improvement rate, recurrence rate, complication rate, pregnant rate, etc. ResultsWe included 7 trials comparing interventional embolization with laparoscopic surgery, including 1 prospective study and 6 retrospective studies, with a total of 349 patients receiving interventional therapy and 400 patients receiving laparoscopic surgery. Meta analysis of the included studies showed that there were no significant differences for sperm improvement rate[OR=1.17, 95%CI (0.70, 1.96), P=0.54], pregnant rate[OR=0.58, 95%CI (0.29, 1.13), P=0.11], recurrence rate[OR=0.84, 95CI% (0.40, 1.78), P=0.66] or complication rate[OR=0.68, 95%CI (0.34, 1.32), P=0.25] between the two groups. ConclusionPresent evidence shows that there is no significant difference between interventional embolization and laparoscopic surgery for varicocele.
ObjectiveTo explore the clinical characteristics and improve the knowledge of diagnosis and treatment of complex pulmonary arteriovenous fistula (PAVF) as well as enrich the experience of diagnosis and treatment of the disease.MethodsA retrospective analysis of pathogenetic process clinical manifestations, imaging features and diagnosis and treatment was conducted on one case of complex PAVF. The literature review was carried out with " complex pulmonary arteryovenous fistula (malformation)” as the research terms in English and Chinese respectively in CNKI, WanFang and PubMed database. Search time ranged from January 1997 to April 2018, and the literature was screened and reviewed.ResultsThe patient was a 47-year-old female complained of recurrent epistaxis for 40 years, intermittent hemoptysis for 20 years, headache, dizziness, chest pain, chest tightness for 4 years and the symptoms were aggravated by 3 months, visiting this hospital on January 23, 2018. Pulmonary CT angiography revealed multiple nodules in internal and external segment and outer basal segment of right lung, anterior basal segment and outer basal segment of left lung. CT enhanced scan showed that the thickened pulmonary artery was connected with the above lesion, and the edge was accompanied by large draining veins. Pulmonary artery revascularization showed complex PAVF abnormal branches. The diagnosis was complex PAVF, and interventional embolization therapy was carried out and curative effect was satisfactory during the follow-up. A total of 6 literatures were reviewed in above-mentioned databases, including 4 Chinese literatures and 2 English literatures, containing 10 patients, including 8 males and 2 females, with an average age of (9.7±7.0) years. Most of the clinical manifestations were shortness of breath after exercise, cyanosis and hemoptysis and all patients were cured and discharged after interventional embolization treatment except for 1 patient refused treatment.ConclusionsComplex PAVF is a very rare pulmonary vascular malformation. The clinical manifestations mainly include hypoxemia, dyspnea, hemoptysis, and the preferred treatment is interventional embolization, which has a satisfactory clinical effect at a short-term follow-up.
ObjectiveTo explore the risk factors for cerebral thrombosis due to interventional embolization of intracranial aneurysms.MethodsThe clinical data of 240 patients with intracranial aneurysms treated by interventional embolization in Department of Neurosurgery, Renmin Hospital of Wuhan University between January 2015 and December 2019 were collected retrospectively. According to whether cerebral thrombosis occurred after embolization, the patients were divided into the cerebral thrombosis group and the non-cerebral thrombosis group. Univariate analyses and multivariate logistic regression analysis were used to analyze the independent risk factors for cerebral thrombosis due to interventional embolization of intracranial aneurysms.ResultsOf the 240 patients, 55 (22.9%) had postoperative cerebral thrombosis confirmed by MRI, and 15 (6.2%) had neurological symptoms. There were significant differences in age, hypertension, hyperlipidemia, operative duration, and procedure methods (simple coiling, balloon or stent-assisted coiling) between the cerebral thrombosis group and the non-cerebral thrombosis group after embolization of intracranial aneurysms (P<0.05). Multivariate logistic regression analysis showed that only operative duration [odds ratio=1.036, 95% confidence interval (1.018, 1.054), P<0.001] was the independent risk factor for cerebral thrombosis after interventional embolization of aneurysms.ConclusionsOperative duration is the independent and adjustable risk factor for cerebral thrombosis after embolization of intracranial aneurysms. Improving the surgical skills of neurointerventional surgeons and shortening the procedure time will be helpful to reduce the occurrence of cerebral thrombosis after interventional treatment of aneurysms and improve the prognosis of patients.
